Question

there are 55 6th graders and 85 8th graders at a middle school. of these students, 35 have dogs and 12 have cats. what is the percentage of people who have dogs

Answer 1

To calculate the percentage of people who have dogs, we first need to find the total number of students and the number of students who have dogs.

1. **Total number of students**:
\[
\text{Total students} = 55 \text{ (6th graders)} + 85 \text{ (8th graders)} = 140
\]

2. **Number of students who have dogs**:
\[
\text{Students with dogs} = 35
\]

3. **Now, calculate the percentage of students who have dogs**:
\[
\text{Percentage of students with dogs} = \left( \frac{\text{Number of students with dogs}}{\text{Total number of students}} \right) \times 100
\]
\[
\text{Percentage of students with dogs} = \left( \frac{35}{140} \right) \times 100
\]
\[
\text{Percentage of students with dogs} = 0.25 \times 100 = 25\%
\]

Therefore, the percentage of students who have dogs is **25%**.
